2 Claims.

This invention relates generally to slicing machines.

One of the objects of our invention is to provide in a machine of the character described having a circular cutting blade, highly improved means for grinding or sharpening the cutting edge of said blade.

Another object of our invention is to provide a compact and rugged grinding device of the character described adapted for use in sharpening blades of cutting machines, which shall comprise relatively few and simple parts, which shall be relatively inexpensive to manufacture, which shall be simple and safe to operate, and at the same time shall be highly efficient.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

Certain features shown and described but not claimed in this application, are shown, described and claimed in our Patent No. 2,119,760, dated June '7, 1938, for Slicing machine of which the present application is a division.

The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts which will be exemplified in'the construction hereinafter described, and of which the scope of application will be indicated in the claims.

In the accompanying drawing, in which is shown one of the various possible embodiments of this invention,

Fig. 1 is a side elevational view of a portion of a slicing machine embodying my invention;

Fig. 2 is a top plan view thereof, but with the sharpening device removed;

Fig. 3 is a view of a portion of the machine shown in Fig. 1, but illustrating the sharpening device in a different position, and

Fig. 4 is a cross-sectional view taken on line 44 of Fig. 3,

Referring now in detail to the drawing, there is shown a portion of a slicing machine l2 of the type, such as is shown and described in our Patent No. 2,119,760, dated June 7, 1938, for Slicing machine. The machine I2 comprises a base l5 on which is supported a housing 22 substantially closed on one side by wall 23 and open on the opposite side, and having an end wall 24 at one end and a top wall 25 at the top continuous with said end wall. Rotatably mounted on said wall 23 is a shaft 26 to which there is fixed a pinion 21 and a circular cutter blade or knife 28. The blade 28 has an inclined edge surface 28a on one side and a fiat surface 281) on the opposite side thereof. The .wall 23 is provided with an outwardly extending boss 36 forming a bearing for a shaft 3|, to the outer end of which there is fixed a crank handle 32. Fixed to the inner end of the shaft 3| is a pinion 33 meshing with the pinion 21.

It will now be understood from the above-described construction that upon rotating the crank handle 32, the blade 28 will be caused to rotate. As shown in Fig. 1, the wall 23 is cut away as at 29, to expose a portion of the cutting edge or periphery of the blade 28.

By our invention we have provided the following novel, safe and convenient means for sharpening the rotary blade 28. Extending from the wall 23 f the blade housing 22 and adjacent the top wall 25, is a lug 40 having an opening 4| disposed in a substantially vertical plane, and a second opening 42, angularly inclined with respect to the opening 4|. Thereis provided a sharpening member 43 comprising a curved portion 45 having a handle portion 46 at one end thereof and being provided with a projecting pin 41 at the opposite end. At an intermediate portion thereof the portion 45 is provided with a bearing 48 adapted to receive therethrough a shaft 49. Mounted on one end of the shaft 49 is a grinding or sharpening wheel of suitable material 50, and fixed to the other-end of the shaft 45 is a nut to hold the wheel 50 in proper position.

It will be noted that when the pin 41 is received within the opening 4|, the grinding Wheel 50 will be disposed in a substantially vertical plane and may be laterally moved by manipulating the handle portion 46 against the flat surface 28b of the blade 28. Also by our construction, it is seen that the member 45 may be raised to withdraw the pin 41 from the opening 4| and inserted within the inclined opening 42 to angularly incline the wheel 50 with respect to its former vertical plane, as shown in Figs. 3 and 4 of the drawing. By manipulating the handle 46, the wheel 50 may then be suitably brought into contact with the inclined surface 28cc of the blade. When the grinding wheel 50 is positioned so as to .contact either of the blade surfaces 28 or 281), rotation of the blade 50 by the handle 32 will cause a quick and effective sharpening of the blade. When the sharpening member 43 is not in effective use, it may be removed from the lug 40.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. In combination, a slicing machine, a cutting blade thereon having a flat surface on one side and an inclined surface on the other side, a housing for said blade, a grinding device comprising a longitudinal member provided with a projecting pin at one end thereof and a grinding wheel rotatably mounted on said longitudinal member intermediate the ends thereof, and means for supporting said device in one position for grinding the fiat surface of said blade and in another position for grinding the inclined surface of said blade, said last named means comprising a pair of openings in said blade housing adapted to selectively receive therein said projecting pin, said pin being rotatable in each of said openings so that the said member may be manually moved to vary the pressure of said wheel against the edge to be sharpened.

2. In a slicing machine, a rotary blade, a housing therefor, said housing being provided with an opening disposed in a vertical plane and an opening disposed in a plane inclined to said vertical plane, and a member having a pin adapted to be selectively received in said openings, and a grinding wheel on said member adapted to sharpen said blade, said pin being rotatable in said openings so that the said member may be manually moved to vary the pressure of said wheel against the blade edge to be sharpened.
